Heart Facts

Heart disease and stroke are the first and fourth leading causes of death in the U.S.

Air pollution can affect heart health and can trigger heart attacks and strokes that cause disability and death.

One in three Americans has heart or blood vessel disease and is at higher risk from air pollution.

EPA is raising awareness of heart disease and its link to air pollution and other environmental factors as a partner in the Million Hearts, a national initiative to prevent 1 million heart attacks and strokes by 2017.
